Pumping of twin-trap Bose-Einstein condensates
M. J. Steel, D. F. Walls
We consider extensions of the twin-trap Bose-Einstein condensate system of Javaneinen and Yoo [Phys. Rev. Lett., 76, 161--164 (1996)] to include pumping and output couplers. Such a…

Collisional matter-phase damping in Bose-condensed gas
L. I. Plimak, M. J. Collett, D. F. Walls
Collisional damping of the excitations in a Bose-condensed gas is investigated over the wide range of energies and temperatures. Numerical results for the damping rate are presente…
